Reviewer: GANG SHEN  -  View all my reviews
My experience was only thirteen dives and it is my first regulator. I selected it because its oxygen range can reach 80%. It will be easy for future other diving equipment condition request.

Questions and Answers for Atomic M1 Monel Regulator:

  • Todd:

    I do a lot of wreck diving in warmer water off the NC coast. I am comparing the Atomic M1, Atomic Z2X and the ScubaPro Titan Legend LX. Can you recommend the best one for the money? I rarely will dive in water colder than 55 degrees. I am planning on using Nitrox as well in the future. Thank you

    Bob  (Certified Scuba Instructor at

    The Legend and Titan are Aqualung products and are 2 different models of 1st Stage. Atomic makes extremely high quality products but the only reason to go with the M1 would be if you are planning on engaging in mixed-gas diving. The Atomic regulators all share the same internal parts with the materials they are made of being the difference. The performance will be next to identical, so the Z2X would be the regulator to choose based on your questions.

  • Kraig:

    I do mostly public safety diving in zero visibility (muddy water) with great extremes in water temperature (up to ice diving). Which would you recommend of the atomic m1 and apeks xtx 200. thanks

    Darrick  (Certified Scuba Instructor at

    Hello Kraig, I would suggest the Apeks XTX 200. With what you are doing that will be a better regulator for your needs.

  • rex:

    Hi my name is Rex, I work cleaning the bottom of boats. I use my regulator 30 Hrs. per week. Im looking for good a regulator that wont need a lot of service, the 1st stage is always on dock, it will probley never go underwater. Would you recomend the Atomic M 1?

    Chance  (Certified Scuba Instructor at

    Yes, this would be a perfect 2nd stage for that purpose. With the monel parts it is very resistant to corrosion. High performance and high durability.

Atomic Aquatics M1 Regulator
Why Monel?
The M1 employs state-of-the-art metals specifically chosen for extreme diving situations. Monel parts are used internally in the first stage for high strength, corrosion-resistance and oxygen compatibility. 316 Stainless Steel, multi-layer Zirconium coated Brass, and Titanium are used throughout the second stage. The M1 valve body is Zirconium/Nickel over Brass and the seat saving orifice is Stainless Steel.

Designed For Challenging Conditions
Engineered by Atomic for specialty diving – rec or tech
The M1 has an expanded performance range to meet almost any diving condition imaginable, whether Recreational or Technical. Accomplished specialty divers will appreciate this regulator designed to fulfill virtually any need or diving scenario. The M1 is built on the same platform as the world acclaimed T2 and B2 regulators.

First Stage:

Factory ready for Nitrox to 50% or oxygen mixes to 80% when special guidelines are followed
First stage materials are chrome plated Brass for the body and Monel for key internal components
Atomic Jet Seat high-flow piston first stage
Freeze protected factory-sealed first stage also prevents contamination such as silt and sand
First stage ports: 2 HP fixed / 5 LP on swivel cap

Second Stage:
Designed for cold water diving featuring thermal heat sink and improved super-dry exhaust valve
Second stage components are made of precision machined Brass with Zirconium plating and Titanium
Patented Atomic Seat Saving Orifice
Patented Atomic Automatic Flow Control (AFC)
A new high-flow second stage case lowers breathing effort at any depth from shallow water to beyond the limits
Rapid adjustment knob for manual second stage de-tuning in special situations
Surge protected second stage front cover for high current scenarios
Super-wide exhaust deflector to disperse bubbles for enhanced visibility
Dual silicone comfort fit mouthpiece with tear-resistant bite tabs
2 year/300 dive service interval
Limited Lifetime Warranty – not contingent on proof of service

Here are some important answers to frequent questions regarding Atomic regulators...

What is Natural Breathing?

Atomic Aquatics has achieved what no other manufacturer has in a high-performance regulator – Natural Breathing. All Atomic regulators breathe with a natural and controlled air delivery sensation at any depth or breathing rate. Inhalation on the surface will feel the same as it does during your deepest dive. This is in part due to the AFC (Automatic Flow Control) employed in our second stages. This patented innovation is a simple device that adjusts the airflow automatically to compensate for the effects of depth. Atomic Aquatics regulators are the smoothest breathing regulators available...period.

What are the diving benefits of Titanium?

First, it is unbelievably lightweight which reduces stress during your dive and makes it a perfect travel regulator. Second, Titanium has no equal for corrosion resistance which means more safety, reliability and repeatable performance. And finally, its beautiful appearance stands apart from any other regulator.

Unparalleled light weight means less stress

In our mission to invigorate the diving experience, the first priority is on reducing stress – travel stress, gearing-up stress, jaw-clinch stress. The best way is to use the lightest material possible. But light weight must never compromise strength or durability. Titanium is the perfect solution. When you hold a Titanium Atomic regulator in your hand, you immediately realize the difference from other regulators. That means less stress for you from packing your gear bag, to donning, to even the final minutes of a long dive.

Atomic M1 Regulator

The Atomic M1 is geared towards those divers who like to mix up their breathing gasses and maybe push the limits a little bit. It is enriched air compatible up to 80% oxygen due to the combination of internal parts made from Monel, a metal widely known for its corrosion resistance, very high strength and most importantly very low friction rate making it extremely oxygen compatible. This gives it the same extreme high quality in construction being combined with state of the art, cutting edge materials still at a quite reasonable price compared to other choices in the category. The addition of a swivel cap on the first stage for the low pressure ports offers the diver high performance, cutting edge technology and unmatched comfort in the various potential configuration possibilities.

Internally this first stage delivers consistent air to the diver with a balanced flow-through piston that will offer the same intermediate pressure with each breath at the deepest depths or lowest tank pressures of your dive. The high pressure piston uses a seal system that is self lubricating that is designed to minimize the friction in this critical part and reduce wear and tear and in turn maintenance costs for the regulators owner

And as if all of this technology and innovation in the Atomic 1st Stages wasn’t enough, their 2nd Stages are packed with one feature after the next all geared towards ease of breathing, longevity of the piece of equipment and low maintenance. The M1 uses an adjustable, pneumatically balanced poppet incorporated into a portion of the regulator that many manufacturers are looking for ways to cut corners and reduce costs in materials. Here, Atomic leads the way by using Titanium, Zirconium, Stainless Steel and Kevlar in all the key common metal parts. For most manufacturers that would the highlights to every single advertisement and mention of this product, but not with Atomic. They pressed on with redesigning two other important pieces in the 2nd stage that turned out to be so successful they were awarded patents for their efforts! The Seat Saving Dynamic Orifice was designed to reduce wear and tear on the low pressure seat and in turn increase the high performance of the second stage for the diver by making sure the orifice only comes into contact with the low pressure seat when the regulator is pressurized. The other innovation is their Automatic Flow Control. Most every manufacturer of regulators offer some sort of a venturi switch in their second stages designed to reduce breathing resistance and help with the opening of the valve that delivers air to the diver when they inhale. At Atomic they’ve perfected this into a pressure sensing, self-adjusting device that regulates the delivery of the diver’s air with every breath adjusting for increased pressure the deeper the diver descends. No more switches or dials to get that perfect breath of air!

With all of this innovation and technology packed into the M1, it is no wonder that this regulator is seen as a “must have” by many technical divers around the world and probably will for years to come.
